TECHNICAL FIELD

The present invention focuses on the field of providing solar powerincluding but not limited to residential and commercial power systemsand arrays. In particular it relates to processes, devices, andcircuitry that can provide such power in a more efficient manner. Italso can find application in general power systems that have some of themore fundamental attributes of solar power sources with the sameeffects.

BACKGROUND

The value of solar power for society has been known for many years. Itoffers clean energy but requires harnessing the energy and feeding itinto electrical grid or other load. Efficiency in generation is ofparticular interest. One aspect that has proven particularly challengingis the ability to harvest the energy efficiently across the entire powerspectrum desired. Because the influx of solar energy can vary andbecause the photovoltaic effect itself can vary, electrical challengesexist that to some degree remain. In addition to the technical issues,regulatory limits such as desirable for safety and the like can alsopose challenges. In addition, the combination of photovoltaic sourcessuch as in the strings of panels or the like combines to make efficientharvesting of the energy an issue. As an example, an interesting factthat is frequently under the current technology the most efficientgeneration of power (likely at the highest voltage after conversion) isa situation where no substantial power is delivered. This seemingparadox is an issue that remains challenging for those in the field.Similarly the desire to generate more and more power such as throughlarger strings of panels has become an issue due to regulatory limitsand the like.

The present invention provides circuits and methods through which manyof these challenges can be reduced or even eliminated. It providesdesigns with unusual efficiency in power generation and providesconsiderable value to those desiring to utilize solar or other powersources efficiently.

MODE(S) FOR CARRYING OUT THE INVENTION

As mentioned earlier, the present invention includes a variety ofaspects, which may be combined in different ways. The followingdescriptions are provided to list elements and describe some of theembodiments of the present invention. These elements are listed withinitial embodiments, however it should be understood that they may becombined in any manner and in any number to create additionalvariations. The variously described examples and preferred embodimentsshould not be construed to limit the present invention to only theexplicitly described systems, techniques, and applications. Further,this description should be understood to support and encompassdescriptions and claims of all the various embodiments, systems,techniques, methods, devices, and applications with any number of thedisclosed elements, with each element alone, and also with any and allvarious permutations and combinations of all elements in this or anysubsequent application.

As shown in FIG. 1, solar power generation can involve accepting onemore sources of power (1) such as may be generated by one or moreindividual photovoltaic sources (2). As is well known, the photovoltaicsource can be a solar panel (19) (as shown in FIG. 6) or even individualsolar cells (20) (also as shown in FIG. 6). In FIG. 1, the sources (2)can be aggregated to create one conceptual photovoltaic source of power(1). The individual output (3) from one of the photovoltaic sources (2)may be a DC power output. This DC power output (3) can be converted intoa modified version of DC power. This may, but need not occur at themodule level, such as by a module or other type of converter which isnot shown but which could, but need not exist for each panel (19) oreach photovoltaic source (2). Such a converter may be configured tooperate on or with individual panels or modules and can control powerharvesting to achieve individual maximum power point operation as isknown.

As mentioned, in an embodiment of the present invention such as shown inFIG. 1, the output of a collection of solar panels or more generallysources (2) can be aggregated to create one conceptual photovoltaicsource of power (1). This, perhaps aggregated, source of power, also aDC power output, and here considered a first photovoltaic source ofpower (5), may be further handled or converted by a DC-DC photovoltaicconverter, perhaps here shown as a base phase DC-DC photovoltaicconverter (6) to provide a base phase switched output (71).

Similarly, another aggregated source of power, here considered a secondphotovoltaic source of power (7), may also be converted by a DC-DCphotovoltaic converter, here shown as an altered phase DC-DCphotovoltaic converter (8) to provide an altered phase switched output(72). Both the base phase DC-DC photovoltaic converter (6) and thealtered phase DC-DC photovoltaic converter (8) can have their outputscombined through combiner circuitry (9), to provide a conversioncombined photovoltaic DC output (10). In addition, both the base phaseDC-DC photovoltaic converter (6) and the altered phase DC-DCphotovoltaic converter (8) can be similarly controlled, such as througha synchronous phase control (11) that synchronously operates switches orthe like in the two converters so their operations are switch timingresponsive in sync with each other, whether opposing or otherwise. Boththe base phase DC-DC photovoltaic converter (6) and the altered phaseDC-DC photovoltaic converter (8) can be considered combined as togetherpresenting a low photovoltaic energy storage DC-DC photovoltaicconverter (15) which can act on two sources or power (1) and can providea low photovoltaic energy storage DC output (65). These outputs may becombined to present an array or other enhanced low photovoltaic energystorage DC output (66).

In typical applications, it is common for the conversion combinedphotovoltaic DC output (10) to be provided as an input to a load, shownas a photovoltaic DC-AC inverter (12) as but one possibility. Thephotovoltaic DC-AC inverter (12) can provide a photovoltaic AC poweroutput (13). This may be connected to a grid or the like. As also shown,strings of such power can be connected in parallel (14) to providegreater power to the photovoltaic DC-AC inverter (12). It is alsopossible to provide an integrated system such as by having both the lowphotovoltaic energy storage DC-DC photovoltaic converter (15) and thephotovoltaic DC-AC inverter (12) integrated to present a combined highefficiency DC-DC-AC photovoltaic converter (16).

In operation, the system can accept first power from the firstphotovoltaic source of power (5), accomplish base phase DC-DC conversionto create a base phase DC power delivery through the base phase DC-DCphotovoltaic converter (6). In similar fashion accepted power from asecond source of power such as the second photovoltaic source of power(7) can be converted through an altered phase DC-DC converting processto provide and create an altered phase DC power delivery. Both the basephase DC-DC photovoltaic converter (6) and the altered phase DC-DCphotovoltaic converter (8) can have switches to achieve theiroperations. These switches can be controlled by some type of controllerperhaps a synchronous phase control (11). The output of the alteredphase DC power delivery and the base phase DC power delivery can becombined to achieve the mentioned conversion combined photovoltaic DCoutput (10). To allow for greater power generation, it is possible thatthe process of combining the different power deliveries can involve theprocess of series combining the power deliveries. The combiner circuitry(9) can be configured as series power configured circuitry so thatvoltage or the like of the two power generators are added. As discussedlater in reference to FIGS. 4, 6, and 7, it can be understood that thecombiner circuitry (9) can involve one or more of either or both aninductance and/or a capacitance. These elements can be configured tohave unusually low energy storage requirements for a photovoltaicsystem, and so the present invention can achieve unusually low input andoutput converter energy storage as discussed later. In such aconfiguration, the circuitry can be considered as involving a lowphotovoltaic energy storage inductor (17) and/or a low photovoltaicstorage capacitor (18) of which the low photovoltaic energy storageDC-DC converter (59) is comprised. When configured as a series powercombining circuit, the combiner circuitry (9) can present additivevoltage circuitry that adds the output voltage of one power supply suchas the base phase switched output to the output voltage of another powersupply such as the altered phase switched output. The step of addingvoltage can allow greater power generation or delivery efficiency whilenot exceeding the regulatory limits as mentioned earlier. It can also beachieved by low inductance adding of the voltages through the teachingsof the present invention.

As mentioned, the converters can be based on a switch-mode type ofoperation. Such converters can have a number of different switchesthrough which operations can achieve the desired goals. Varying types ofconverters are shown in different embodiments of the present invention.As shown in FIGS. 4, 5, 6, and 7, the converters can have switches(e.g., 21-46) that can be controlled to achieve the desired goals. Thiscontrol can be specific to embodiments of the present invention and canbe an important aspect in achieving the goals as desired as well as animportant difference in operation as compared to previous similarcircuitries. Further, some of the switches such as those labeled (44 &45 and the like) can be active switches, diodes, or even a combinationof diodes with an active switch. The affirmative control of the switchescan be by the synchronous phase control (11) as mentioned earlier. Asshown in FIG. 1, one literal or conceptual synchronous control canactivate multiple converters so that their switches are synchronous inoperation. Naturally, two or more separate controls with a common timingcan be used as long as their clock cycles are common so that the twoconverters are operated under one timing mode.

Control can be by duty cycle controlling the switches in the converters.A duty cycle controller (51) can be provided common to both convertersas shown, and as such it can be considered a common duty cyclecontroller to achieve the step of common duty cycle control so thatswitches in the two converters can be operated synchronously accordingto desired schedules. By providing a common controller or at leastsynchronously controlling the converters, embodiments of the inventioncan be considered as providing a common timing signal for switchoperation. This common timing signal can specifically cause modes ofoperation in accordance with the invention. For example, FIGS. 2a and 2bshow some examples of this common timing signal for the tappedmagnetically coupled inductor embodiments of the invention such as shownin FIG. 4. In these figures, a roughly 25% (FIGS. 2b ) and 12½% (FIG. 2a) duty cycle operation is conceptually presented showing the operationof switches (21-28) as indicated. Although not shown, operation from 0%to 100% is possible, of course. As may be understood in the context ofcomparing the operations of switches (21 & 24), switches (26 & 27),switches (22 & 23), and switches (25 & 28) the synchronous and opposingmodes of control can be seen. These switches can be sequentiallyoperated so that the outputs of each converter oppose each other andswitched at different times. As may be appreciated from FIG. 2b , thiscan offer advantages such that the opposing modes of operation cancompensate for and offset an effect of each other in the combinercircuitry (9) and thus allow lower energy storage and more efficientoperation. By presenting an opposing phase controller (52), embodimentsof the invention can be configured such that one converter is on,generating power, active or the like when another is off or the like andvice versa. Through such affirmative control of switches, opposing phasecontrolling of the step of converting the power can achieve thereductions in energy storage as well as reduced ripple and otheradvantages. This opposing phase controller (52) can be diametricallyopposing such as by providing a 180° photovoltaic converter switchcontroller and 180° photovoltaic converter switch controlling the DCoutput or the converters as shown. In this fashion the convertercomponents can deliver power according to an interleaved schedule orprocess to effect advantages mentioned.

Similarly, by the interleave design, advantages can also be achieved.This can the understood conceptually with reference to FIGS. 3a-3d withthe bottom axis representing the percentage of duty cycle operation.Perhaps non-quantitatively, FIG. 3a can be understood as representing anefficiency type of value (actually inefficiency) across the duty cyclesranges. It also compares one traditional operation with some of theimproved modes of operation. In the previous systems, converters mayhave presented efficiency (or more appropriately inefficiency) across a0% to 100% duty cycle range as shown conceptually in FIG. 3a by thecurve labeled (53). By understanding that for some values and in someinstances the FIG. 3a conceptual plot can be considered as presentinginefficiency or even a conversion energy along a vertical axis, it canbe seen that significant inefficiency exists for many traditionalsystems at anything other than the 0% and 100% duty cycle areas. Fromthis, it can be conceptually understood that in many traditionaloperating modes (designs with a full duty cycle energy configuration),converters were often least efficient at a midpoint of operation. Theywere most efficient at the 0% duty cycle of operation (no power) andalso at the 100% duty cycle mode of operations (no conversion) but thesecan be less significant from a conversion perspective. Thus as thoseskilled in the art well understood, during the most significantsituations of power generation or at least delivery, such as in the 50%to 100% duty cycle range of operation—often the most commonlocations—the converter was on average not that efficient. For example,for a maximum 60 volt panel output, a more traditional, full cycleripple energy converter could provide an output ranging from 0 to 60volts. At 0% duty cycle (0 volts), there was no power delivered; at 50%duty cycle there was power but at worst efficiency; at 100% there was noconversion achieved. Embodiments of the present invention show that thismode of operation can be improved upon. As explained later, entireefficiency is enhanced by the phased modes of operation now availablethrough the present invention.

With respect to the curve labeled as (54), one can understand that thisparticular mode shows operation of embodiments designed to achieve ahalf duty cycle energy configuration. As may be conceptually understoodfrom this plot, the efficiency can be improved (inefficiency reduced)through embodiments of the present invention. Similarly in the curvelabeled (55), an operation mode using a half duty cycle energyconfiguration with or without the phased operational mode can beunderstood. As shown, even further advantages can be achieved (this maynot be available for some of the embodiments of the present invention).Even the aspect of varying the voltage across all operational regimes ischanged for embodiments of the present invention. Output voltage doesnot vary in this manner for the present invention, it remains relativelyconstant and so a high delivery voltage (itself a more efficient way todeliver power) can be achieved.

FIG. 3b can be considered as indicating amount of ripple such as throughthe low photovoltaic storage energy inductor (17) or the like. FIG. 3bcan also be considered as indicating ripple current energy. FIG. 3c canbe considered as indicating the sweet spot character across the variousduty cycles. The number of sweet spots available in operation, withsubstantial power delivery, for the high efficiency conversionoperations according to the present invention is improved. Sweet spots(highest practical efficiency and/or relatively little or noinefficiency) can be understood to exist at locations on the plot whereit touches the bottom axis. A sweet spot can exist for some traditionalcircuitry at 0% and 100% of operation. Unfortunately, these are oftenlocations of least interest as they may be less common or at least maynot involve substantial power delivery. In embodiments of the presentinvention, sweet spots can exist at 50% and 100% or even at 25% and 50%.Through such designs and mode of operation, embodiments can thus providean augmented sweet spot photovoltaic output. These augmented sweet spotscan now exist even at substantial power conversion locations ofoperation and can be an effect caused by the new opposing phase mode ofoperational control by the synchronous control (11). As shown in FIG. 3c, for embodiments of the present invention, a sweet spot can now existeven at locations where significant power conversion occurs, not just atextremes of operational modes as in many traditional designs. Thus, theinvention can provide a converted power generation or delivery sweetspot photovoltaic output as well as an augmented sweet spot photovoltaicoutput. As is well known, solar panels can have temperature effects;they generate power differently in different temperature conditions, andto a significant extent the variation in duty cycle can be due to this(as well as partial shading, etc.). In fact, the depiction in FIG. 3dcan be considered as indicating a temperature effect on efficiency witha hot temperature power generation condition more likely at the 100%duty cycle and a cold temperature power generation condition more likelyat the 50% duty cycle for maximum power harvesting. For many traditionalsystems operation at a colder temperature had a mode of relatively lowerconversion efficiency. Through embodiments of the invention, highefficiency can exist at such reduced temperature power generationconditions and the invention can thus present a photovoltaically reducedtemperature condition sweet spot photovoltaic output. For certaindesigns, it can even present a cold operational regime sweet spotphotovoltaic output. As shown in FIG. 3c , for embodiments of thepresent invention, a sweet spot can exist at the 50% duty cycle rangerather than a poorly efficient level of power delivery, not just a topas in many traditional designs and so the invention can provide a coldoperational regime sweet spot photovoltaic power output.

As mentioned above, converters may be affirmatively switched to achievebest modes of operation. A variety of converter topologies are possibleand several are shown in the figures. FIG. 5 shows a particular type ofconverter as applied to an individual panel that has a tappedmagnetically coupled inductor element (56). This is one example of atapped magnetically coupled inductor arrangement. As shown the tappedmagnetically coupled inductor element (56) has an inductor tap (57).This embodiment is affirmatively switched through switches (31 through42) for the various converters as shown in FIG. 5. These switches areactivated by a duty cycle controller (51) to which the converter isswitch timing responsive. As shown, this converter can include two pairsof series switches (e.g., 31 & 33) (32 & 34) connected at midpoints (58)at which the tapped magnetically coupled inductor element (56) isconnected. Each low photovoltaic energy storage DC-DC photovoltaicconverter (59) can include its own low photovoltaic energy storageinductor (60) and low energy storage output capacitor (61) so as toprovide a low photovoltaic inductance DC output (62). FIG. 5 showsmultiple applications of the tapped magnetically coupled inductorarrangements whereby each converts its own power output, perhaps such asfrom a solar panel (19). These converted, high efficiency photovoltaicoutputs (62) may be series combined as shown to present an outputstring. Only a portion of a typical string is depicted. Often numerouspanels are combined to approach the maximum allowed operating voltage.In this embodiment, however, an excess voltage arrangement can beconfigured. By using a half duty cycle energy configuration andindividual power source conversion as shown, the string can beconfigured to provide a double maximum voltage arrangement such that amaximum regulatory or other allowed output can be one-half of thetheoretically available panel voltage output. To stay under the maximumamount, the output can be boundary limited by including a photovoltaicboundary output controller (63) which may be part of each individualduty cycle controller, as depicted, or which may be conceptually acollective control for all converters in the string. For configurationsapplying a quarter duty cycle energy configuration and the individualpower source conversion as shown, the string can even be configured toprovide a quadruple maximum voltage arrangement such that a maximumregulatory or other allowed output can be one-quarter of thetheoretically available panel voltage output. Additional duty cycleenergy options (one-eighth, one-tenth, etc.) are also possible, ofcourse. Again, a photovoltaic boundary output controller (63) can beincluded. Importantly, even with this boundary limitation, power isstill harvested efficiently. Embodiments of the invention can beextremely efficient as compared to traditional designs. In fact, theinvention can present a photovoltaic output that is at least about 98%,99%, and 99.5% efficient from the perspective of its conversion processacross a duty cycle range (averaged across the range of operation, anoccurrence-based range of delivery, or a range of typical expectedoperation). It can even approach only wire losses in delivering power.Traditional designs rarely can achieve this level of efficiency.

For embodiments utilizing phased operational modes, interconnection andoperation such as shown in FIG. 4 can be achieved. In this embodiment,the two pairs of series switches (e.g., 21 & 23)(22 & 24) connected atmidpoints (58), can have the output from the tapped magnetically coupledinductor element (56) combined such as through the low photovoltaicenergy storage inductor (17) so as to provide a low photovoltaicinductance DC output (64), and also a low energy storage outputcapacitor (18) to present another type of low photovoltaic energystorage DC-DC photovoltaic converter (59). In similar fashion to that ofthe individual panel conversion design of FIG. 5, the arrangement ofFIG. 4 can also have an excess voltage arrangement. Such configurationscan be of a half duty cycle energy configuration and so a half dutycycle controller can be used with the converted string configured toprovide a double maximum voltage arrangement. In this configuration,again, to stay under the maximum amount, the output can be boundarylimited by including a photovoltaic boundary output controller (63).

Embodiments such as the phased converter shown in FIG. 4 can also beachieved through a buck power converter appearing arrangement such asshown in FIG. 7. In this embodiment circuitry resembling two buck DC-DCpower converters can be used to create one high efficiency convertersuch as the low photovoltaic energy storage DC-DC photovoltaic converter(15) shown. In this embodiment, two pairs of series switches (43 & 44)(45 & 46) connected at midpoints (67) can have the output from theswitched element combined such as through the low photovoltaic energystorage inductor (17) so as to provide a low photovoltaic inductance DCoutput (62), and also a low energy storage output capacitor (18) topresent the low photovoltaic energy storage DC-DC photovoltaic converter(15). FIGS. 9a and 9b show some examples of this common timing signalfor this embodiment. In these figures, a roughly 50% (FIGS. 9a ) and 75%(FIG. 9b ) duty cycle operation is conceptually presented showing theoperation of switches (43-46) as indicated. Again, although not shown,operation from 0% to 100% is possible, of course. As may be understoodin the context of comparing the operations of switches (43 & 44) andswitches (46 & 45), the synchronous and opposing modes of control can beseen. These switches can be sequentially operated so that the outputs ofeach converter oppose each other and are switched at different times. Aswith FIGS. 2a and 2b , this also offer advantages such that the opposingmodes of operation can compensate for and offset an effect of each otherin the combiner circuitry (9) and thus allow lower energy storage andmore efficient operation.

As mentioned earlier, embodiments of the invention can operate at highoperational voltages. Whereas in most, more traditional systems, outputefficiency varied across the operational regime as shown in the curve(53) in FIG. 3, in embodiments of the present invention, the output canbe relatively stable. As also indicated conceptually in FIG. 3 whenconsidering the vertical axis as a type of ripple indication, mainlyjust the ripple varies—and even this is at a lower level of ripple thanprevious. The output voltage can be controlled to be relatively constantacross all operational regimes without any compromise in power delivery.In fact, not only is there no loss in power delivery, the presentinvention can achieve higher power delivery. By utilizing a phasedoperational mode, this power output voltage such as present at theenhanced low photovoltaic energy storage DC output (66) (for theembodiment in FIG. 1), low photovoltaic inductance DC output (64) (forthe embodiment in FIG. 4), and high efficiency photovoltaic outputs (62)(for the embodiment in FIGS. 5 & 7) can be a high multi operationalregime output such that it is, at least in a photovoltaic sense, at arelatively high voltage or the like in any or even across alloperational conversion regimes where substantial power is delivered. Thehigh multi operational regime output can even be a high averagephotovoltaic voltage output (averaged across the range of operation, anoccurrence-based range of delivery, or a range of typical expectedoperation). This high average photovoltaic voltage output or high multioperational regime output can be controlled to be near or even at themaximum desired or allowable for enhanced efficiency, perhaps less someguard band tolerance. Thus, embodiments can be configured or controlledto achieve an at least about 80%, 90%, or even 95% or more of a maximumvoltage photovoltaic output across a typical operational range.

Beyond merely the level of voltage, embodiments can also presentparticular levels of high efficiency such as at sweet spots or the like.Considering the diagram of FIG. 3 as conceptually depicting temperatureeffect with a hot temperature generation at or near the 100% duty cycleand cold temperature operation at or near the 50% duty cycle, it can beunderstood that most significant, nominal operation will often occur inthe 50% to 100% range. As discussed above with respect to the sweetspots shown conceptually in FIG. 3, designs can present dual nominaloperational range high efficiency photovoltaic power outputs where sweetspot operation exists at two substantial power delivery locations. Thisis shown conceptually in FIGS. 3 at 50% & 100% for the embodimentscharacterized as the half duty cycle energy configuration embodiments,and at 50%, 75%, and 100% for the embodiments characterized as thequarter duty cycle energy embodiments. Similarly, embodiments can beconsidered as presenting at least one high efficiency converted powergeneration or delivery mode photovoltaic output such as those referencedabove and may even provide a two or dual high efficiency spots at whichpower conversion or delivery occurs.

In providing a low inductance output or low energy storage conversion,both the energy storage experienced at an input and at an output can beunusually low, at least from a photovoltaic perspective. Inputinductance can be particularly low for the module level converterdesigns. This can be significant and can benefit the applied loadperhaps such as the photovoltaic DC-AC inverter (12). Through propercoordination, this can offer advantages and can even encourage the useof the integrated design such as the combined high efficiency DC-DC-ACphotovoltaic converter (16) design shown in FIG. 1.

As previously mentioned, a low energy storage converter, perhapscomprising a low energy storage, a low energy inductance, and/or a lowenergy capacitance, are advantages of the present invention. Recallingthat FIG. 3 can be viewed as conceptually indicating the amount ofripple current storage energy across the duty cycle range, it can beunderstood that the amount of storage energy is significantly reducedthrough embodiments of the present invention. Whereas traditionalsystems indicate significant energy storage needs equivalent to a fullcycle of ripple energy (as suggested by the peak height of curve (53) at50%), in embodiments of the present invention, this energy can beconsiderably reduced by half or even a quarter as shown. Specifically,for a 50% to 100% design shown by curve (54), the peak height at 25% and75% is about one-half the amount of energy storage indicated for atraditional system with equivalent switching frequency, equivalent typesof switches, and the like. Similarly, for a 25% to 50% design shown bycurve (55), the peak height at about 12½%, 37½%, etc. is aboutone-quarter the amount of energy storage indicated for a traditionalsystem. The reduced values of conversion energy storage, inductance, andcapacitance can be achieved at these reduced levels. Thus, for theembodiments characterized as the half duty cycle energy configurationembodiments, such designs can have a not more than about one-half dutycycle range ripple current photovoltaic energy storage converter, a notmore than about one-half of traditional photovoltaic energy storageconverter, a not more than about one-half duty cycle range ripplecurrent photovoltaic energy storage inductor, a not more than aboutone-half of traditional photovoltaic energy storage inductor, a not morethan about one-half duty cycle range ripple current photovoltaic energystorage capacitor, and a not more than about one-half of traditionalphotovoltaic energy storage capacitor. Similarly, for the embodimentscharacterized as the quarter duty cycle energy configurationembodiments, such designs can have a not more than about one-quarterduty cycle range ripple current photovoltaic energy storage converter, anot more than about one-quarter of traditional photovoltaic energystorage converter, a not more than about one-quarter duty cycle rangeripple current photovoltaic energy storage inductor, a not more thanabout one-quarter of traditional photovoltaic energy storage inductor, anot more than about one-quarter duty cycle range ripple currentphotovoltaic energy storage capacitor, and a not more than aboutone-quarter of traditional photovoltaic energy storage capacitor.Similar aspects can exist for other embodiments (one-eighth, one-tenth,etc.) This can allow greater power delivery to the load such as thephotovoltaic DC-AC inverter (12) or the like.

A further embodiment of the invention is illustrated in FIG. 6. In thisdesign, an individual panel (19) can be enhanced by providing aninterpanel or other conversion design that may be integral to, attachedto, or provided with the panel (19). In this embodiment, multiplephotovoltaic power cells (20) can be aggregated perhaps conceptually topresent a solar panel (19) perhaps in its own assembly. The solar panel(19) power delivery can be conceptually split at some point and so therecan be at least one split panel DC-DC photovoltaic converter (68). Asdiscussed above, this can actually be comprised of two converters,perhaps such as a base phase DC-DC photovoltaic converter (6) and thealtered phase DC-DC photovoltaic converter (8). These converters canhave their outputs combined through combiner circuitry to provide aconversion combined photovoltaic DC output and this type of combinercircuitry can be configured as an interpanel photovoltaic cell additioncircuitry (70).

The split panel DC-DC photovoltaic converter (68) can have affirmativeswitches as shown, that may be controlled by an internal or externalduty cycle controller (51) to provide a high efficiency (or low energystorage or low inductance) photovoltaic DC output (69). Again this canbe configured as to have a tapped magnetically coupled inductorarrangement or a buck converter appearing arrangement. Each can includea low photovoltaic energy storage inductor (17), a low photovoltaicinductance DC output, and a low energy storage output capacitor (18) asdiscussed above. This type of low photovoltaic energy storage DC-DCphotovoltaic converter (59) can achieve the advantages discussed above.It may or may not require a photovoltaic boundary output controller.

As shown in FIG. 8, for those embodiments of any of the above thatinclude a photovoltaic boundary output controller (63), it may beunderstood that this controller can control voltage (73), current (74),maximum power point (75), power delivery (perhaps even by over voltageboundary control to regulate the output power), or other aspects thatmay need to be limited such as to meet regulatory concerns or the like.This may, of course, exist for high temperature operation (76) or lowtemperature operation (77). Voltage control can be the most importantfor regulatory and other reasons, and so embodiments can present somecontroller as a photovoltaic output voltage limit controller. Thephotovoltaic boundary output controller (63) can limit output at aboundary hierarchally, that is with an ordered decisional process as towhich limit applies and overrides other limits as well.

As can be easily understood from the foregoing, the basic concepts ofthe present invention may be embodied in a variety of ways. It involvesboth conversion techniques as well as devices to accomplish theappropriate conversion. In this application, the conversion techniquesare disclosed as part of the results shown to be achieved by the variousdevices described and as steps which are inherent to utilization. Theyare simply the natural result of utilizing the devices as intended anddescribed. In addition, while some devices are disclosed, it should beunderstood that these not only accomplish certain methods but also canbe varied in a number of ways. Importantly, as to all of the foregoing,all of these facets should be understood to be encompassed by thisdisclosure.

The discussion included in this application is intended to serve as abasic description. The reader should be aware that the specificdiscussion may not explicitly describe all embodiments possible; manyalternatives are implicit. It also may not fully explain the genericnature of the invention and may not explicitly show how each feature orelement can actually be representative of a broader function or of agreat variety of alternative or equivalent elements. Again, these areimplicitly included in this disclosure. Where the invention is describedin device-oriented terminology, each element of the device implicitlyperforms a function. Apparatus claims may not only be included for thedevice described, but also method or process claims may be included toaddress the functions the invention and each element performs. Neitherthe description nor the terminology is intended to limit the scope ofthe claims that will be included in any subsequent patent application.

It should also be understood that a variety of changes may be madewithout departing from the essence of the invention. Such changes arealso implicitly included in the description. They still fall within thescope of this invention. A broad disclosure encompassing the explicitembodiment(s) shown, the great variety of implicit alternativeembodiments, and the broad methods or processes and the like areencompassed by this disclosure and may be relied upon when drafting theclaims for any subsequent patent application. It should be understoodthat such language changes and broader or more detailed claiming may beaccomplished at a later date (such as by any required deadline) or inthe event the applicant subsequently seeks a patent filing based on thisfiling. With this understanding, the reader should be aware that thisdisclosure is to be understood to support any subsequently filed patentapplication that may seek examination of as broad a base of claims asdeemed within the applicant's right and may be designed to yield apatent covering numerous aspects of the invention both independently andas an overall system.

Further, each of the various elements of the invention and claims mayalso be achieved in a variety of manners. Additionally, when used orimplied, an element is to be understood as encompassing individual aswell as plural structures that may or may not be physically connected.This disclosure should be understood to encompass each such variation,be it a variation of an embodiment of any apparatus embodiment, a methodor process embodiment, or even merely a variation of any element ofthese. Particularly, it should be understood that as the disclosurerelates to elements of the invention, the words for each element may beexpressed by equivalent apparatus terms or method terms—even if only thefunction or result is the same. Such equivalent, broader, or even moregeneric terms should be considered to be encompassed in the descriptionof each element or action. Such terms can be substituted where desiredto make explicit the implicitly broad coverage to which this inventionis entitled. As but one example, it should be understood that allactions may be expressed as a means for taking that action or as anelement which causes that action. Similarly, each physical elementdisclosed should be understood to encompass a disclosure of the actionwhich that physical element facilitates. Regarding this last aspect, asbut one example, the disclosure of a “converter” should be understood toencompass disclosure of the act of “converting”—whether explicitlydiscussed or not—and, conversely, were there effectively disclosure ofthe act of “converting”, such a disclosure should be understood toencompass disclosure of a “converting” and even a “means forconverting.” Such changes and alternative terms are to be understood tobe explicitly included in the description. Further, each such means(whether explicitly so described or not) should be understood asencompassing all elements that can perform the given function, and alldescriptions of elements that perform a described function should beunderstood as a non-limiting example of means for performing thatfunction.

Any patents, publications, or other references mentioned in thisapplication for patent are hereby incorporated by reference. Anypriority case(s) claimed by this application is hereby appended andhereby incorporated by reference. In addition, as to each term used itshould be understood that unless its utilization in this application isinconsistent with a broadly supporting interpretation, common dictionarydefinitions should be understood as incorporated for each term and alldefinitions, alternative terms, and synonyms such as contained in theRandom House Webster's Unabridged Dictionary, second edition are herebyincorporated by reference. Finally, all references listed in the list ofreferences or other information statement filed with the application arehereby appended and hereby incorporated by reference, however, as toeach of the above, to the extent that such information or statementsincorporated by reference might be considered inconsistent with thepatenting of this/these invention(s) such statements are expressly notto be considered as made by the applicant(s).

Thus, the applicant(s) should be understood to have support to claim andmake a statement of invention to at least: i) each of the power devicesas herein disclosed and described, ii) the related methods disclosed anddescribed, iii) similar, equivalent, and even implicit variations ofeach of these devices and methods, iv) those alternative designs whichaccomplish each of the functions shown as are disclosed and described,v) those alternative designs and methods which accomplish each of thefunctions shown as are implicit to accomplish that which is disclosedand described, vi) each feature, component, and step shown as separateand independent inventions, vii) the applications enhanced by thevarious systems or components disclosed, viii) the resulting productsproduced by such systems or components, ix) each system, method, andelement shown or described as now applied to any specific field ordevices mentioned, x) methods and apparatuses substantially as describedhereinbefore and with reference to any of the accompanying examples, xi)an apparatus for performing the methods described herein comprisingmeans for performing the steps, xii) the various combinations andpermutations of each of the elements disclosed, xiii) each potentiallydependent claim or concept as a dependency on each and every one of theindependent claims or concepts presented, and xiv) all inventionsdescribed herein.

In addition and as to computer aspects and each aspect amenable toprogramming or other electronic automation, the applicant(s) should beunderstood to have support to claim and make a statement of invention toat least: xv) processes performed with the aid of or on a computer,machine, or computing machine as described throughout the abovediscussion, xvi) a programmable apparatus as described throughout theabove discussion, xvii) a computer readable memory encoded with data todirect a computer comprising means or elements which function asdescribed throughout the above discussion, xviii) a computer, machine,or computing machine configured as herein disclosed and described, xix)individual or combined subroutines and programs as herein disclosed anddescribed, xx) a carrier medium carrying computer readable code forcontrol of a computer to carry out separately each and every individualand combined method described herein or in any claim, xxi) a computerprogram to perform separately each and every individual and combinedmethod disclosed, xxii) a computer program containing all and eachcombination of means for performing each and every individual andcombined step disclosed, xxiii) a storage medium storing each computerprogram disclosed, xxiv) a signal carrying a computer program disclosed,xxv) the related methods disclosed and described, xxvi) similar,equivalent, and even implicit variations of each of these systems andmethods, xxvii) those alternative designs which accomplish each of thefunctions shown as are disclosed and described, xxviii) thosealternative designs and methods which accomplish each of the functionsshown as are implicit to accomplish that which is disclosed anddescribed, xxix) each feature, component, and step shown as separate andindependent inventions, and xxx) the various combinations andpermutations of each of the above.

With regard to claims whether now or later presented for examination, itshould be understood that for practical reasons and so as to avoid greatexpansion of the examination burden, the applicant may at any timepresent only initial claims or perhaps only initial claims with onlyinitial dependencies. The office and any third persons interested inpotential scope of this or subsequent applications should understandthat broader claims may be presented at a later date in this case, in acase claiming the benefit of this case, or in any continuation in spiteof any preliminary amendments, other amendments, claim language, orarguments presented, thus throughout the pendency of any case there isno intention to disclaim or surrender any potential subject matter. Itshould be understood that if or when broader claims are presented, suchmay require that any relevant prior art that may have been considered atany prior time may need to be re-visited since it is possible that tothe extent any amendments, claim language, or arguments presented inthis or any subsequent application are considered as made to avoid suchprior art, such reasons may be eliminated by later presented claims orthe like. Both the examiner and any person otherwise interested inexisting or later potential coverage, or considering if there has at anytime been any possibility of an indication of disclaimer or surrender ofpotential coverage, should be aware that no such surrender or disclaimeris ever intended or ever exists in this or any subsequent application.Limitations such as arose in Hakim v. Cannon Avent Group, PLC, 479 F.3d1313 (Fed. Cir 2007), or the like are expressly not intended in this orany subsequent related matter. In addition, support should be understoodto exist to the degree required under new matter laws—including but notlimited to European Patent Convention Article 123(2) and United StatesPatent Law 35 USC 132 or other such laws—to permit the addition of anyof the various dependencies or other elements presented under oneindependent claim or concept as dependencies or elements under any otherindependent claim or concept. In drafting any claims at any time whetherin this application or in any subsequent application, it should also beunderstood that the applicant has intended to capture as full and broada scope of coverage as legally available. To the extent thatinsubstantial substitutes are made, to the extent that the applicant didnot in fact draft any claim so as to literally encompass any particularembodiment, and to the extent otherwise applicable, the applicant shouldnot be understood to have in any way intended to or actuallyrelinquished such coverage as the applicant simply may not have beenable to anticipate all eventualities; one skilled in the art, should notbe reasonably expected to have drafted a claim that would have literallyencompassed such alternative embodiments. Further, if or when used, theuse of the transitional phrase “comprising” is used to maintain the“open-end” claims herein, according to traditional claim interpretation.Thus, unless the context requires otherwise, it should be understoodthat the term “comprise” or variations such as “comprises” or“comprising”, are intended to imply the inclusion of a stated element orstep or group of elements or steps but not the exclusion of any otherelement or step or group of elements or steps. Such terms should beinterpreted in their most expansive form so as to afford the applicantthe broadest coverage legally permissible. The use of the phrase, “orany other claim” is used to provide support for any claim to bedependent on any other claim, such as another dependent claim, anotherindependent claim, a previously listed claim, a subsequently listedclaim, and the like. As one clarifying example, if a claim weredependent “on claim 20 or any other claim” or the like, it could bere-drafted as dependent on claim 1, claim 15, or even claim 25 (if suchwere to exist) if desired and still fall with the disclosure. It shouldbe understood that this phrase also provides support for any combinationof elements in the claims and even incorporates any desired properantecedent basis for certain claim combinations such as withcombinations of method, apparatus, process, and the like claims.

Finally, any claims set forth at any time are hereby incorporated byreference as part of this description of the invention, and theapplicant expressly reserves the right to use all of or a portion ofsuch incorporated content of such claims as additional description tosupport any of or all of the claims or any element or component thereof,and the applicant further expressly reserves the right to move anyportion of or all of the incorporated content of such claims or anyelement or component thereof from the description into the claims orvice-versa as necessary to define the matter for which protection issought by this application or by any subsequent continuation, division,or continuation-in-part application thereof, or to obtain any benefitof, reduction in fees pursuant to, or to comply with the patent laws,rules, or regulations of any country or treaty, and such contentincorporated by reference shall survive during the entire pendency ofthis application including any subsequent continuation, division, orcontinuation-in-part application thereof or any reissue or extensionthereon.
